Arrangement in a Waste Container

ABSTRACT

An arrangement in a waste container furnished with replaceable refuse sack ( 6 ) and having a body supporting the refuse sack from the inside, the purpose of which is to keep by use refuse sack ( 6 ) open substantially in its largest size, when the refuse sack ( 6 ) is together with the said body fitted into a bin construction suitable for the purpose. The inside body is formed of walls of plate construction or, for instance, of net construction ( 2, 3 ), of which at least one wall ( 3 ) is movable in order to increase the volume formed by means of said walls.

The invention relates to an arrangement in a waste container furnishedwith replaceable refuse sack and having a body supporting the refusesack from the inside, the purpose of which is to keep the refuse sack byuse open substantially in its largest size, when the refuse sack istogether with the said body fitted into a waste container constructionsuitable for the purpose.

In known refuse bins the refuse sack is replaced inside the containerbody, whereby the refuse sack gets supported from the outside by use. Inknown solutions the body supporting the refuse sack from the outside isusually a solid wall of plate structure. The filled refuse sack islifted from refuse bin or the container mantle or bottom is detachable,whereby the refuse sack can be removed without lifting it. By use therefuse sack is hidden inside the container.

When it is wanted to do a refuse sack embodiment, where the sack isvisible, the wall that supports the sack may not be outside the sack.The supporting walls must be placed inside the refuse sack. If thereplaceable refuse sack works also as advertising surface havingadvertising printings, the sack surface must be quite smooth and notcreased, in other words, stretched to proper tightness.

Known are arrangements to facilitate removal off and fitting of therefuse sack. onto the body, for instance from patent publications GB109676, U.S. Pat. No. 3,983,914, U.S. Pat. No. 4,037,778, U.S. Pat. No.6,179,150 and U.S. Pat. No. 6,367,747.

The motive of the invention is to present a body supporting a refusesack to be placed into a refuse sack, which body independently andautomatically stretches the advertising surfaces of the refuse sack,whereby the refuse sack is still easily replaceable. The invention ischaracterized in that the inside body is formed of walls of platestructures or for instance of net structures, of which at least one wallcan be moved by means of the force of gravity in order to increase thevolume formed by means of said walls.

Characteristic for the other embodiments of the invention is that whatis presented in the dependent claims.

The advantage of the arrangement according to the invention is that therefuse sack can be made an easily fitted and easily emptied sackalthough it is in usable position tense by means of bodies inside therefuse sack. By means of the arrangement at least a part of the bodiescan be made movable as much as needed so that the refuse sack gets moretense by use and that on replacing the sack so much slack is formed thatthe refuse sack is easily put to rest on the body parts and removed fromthem. The shift of body parts to broader or the narrower position simplytakes place automatically by means of gravitation, when another body islifted.

In the following the invention is disclosed with reference to theenclosed drawing, where

FIG. 1 shows a body meant to support a refuse sack placed in a wastecontainer.

FIG. 2 shows body 1 shifted into broader position,

FIG. 3 shows a portion of the refuse sack made tense by means of thebody parts.

FIG. 1 shows the body to be fitted in refuse bin in order to support therefuse sack. The body is made of an upper frame 1, from which oppositewalls 2 go downward. Other walls 3 are loose from upper frame 1 andfixed to walls 2 by means of oblong diagonally fitted holes 4 and screws5. Thus walls 3 can move outward and upwards from the FIG. 1 position asmuch as the distance of hole 4. Body parts 2 and 3 get inside the refusesack. In an advantageous embodiment the refuse sack getting around thebody parts remains for the most part visible and works as replaceable,when having advertising printings.

In FIG. 2 the body parts 2 and 3 have got upward and at the same timedrawn away from one another. This-happens, for instance, if body partsare placed on an even cover, whereby their bottom edges get on sameheight, which means upward rise of parts 3. The enlargement part of FIG.2 shows a diagonally directed groove 4 for screw 5, the large screw-headdoes not fit through groove 4.

In FIG. 3 the body parts inside refuse sack 6 are at their mostextensive, whereby parts 3 stretch the refuse sack into a square formThe printings on the refuse sack surface get then quite visible.

Instead of plate constructions parts 2 and 3 can be nets, especiallysheets of net. Instead of square construction the body construction canbe round or of some other shape.

Most suitably the body can be without bottom, whereby refuse sack 6 isremoved pulling downwards and the refuse inside parts 2 and 3 fell atthe same time into the refuse sack at the. The body parts are then inthe position of FIG. 1. In this position also a new refuse sack 6 ismounted as replacement. In one embodiment still another refuse sack isplaced inside the body parts, whereby a double protection for theresidue is achieved.

1. An arrangement in a waste container furnished with replaceable refusesack (6) and having a body supporting the refuse sack from the inside,the purpose of which is to keep by use the refuse sack (6) opensubstantially in its largest size, when the refuse sack (6) is togetherwith the said body fitted into a container construction suitable for thepurpose, characterized in that the inside body (2),(3) is formed ofplate walls or, for instance, walls of net construction, of which wallsat least one wall (3) is movable outwards by means of gravitation forcein order to increase the volume formed by said walls.
 2. An arrangementaccording to claim 1 characterized in that movable wall (3) is fitted tomove outwards or inwards by means of gravitation force, whereby thefastening of said wall (3) to other body wall (2) is arranged, forinstance, by means of an oblong diagonally directed hole (4) and afixing means (5) moving in it.
 3. An arrangement according to claim 1characterized in that the container construction comprises a supportingbottom part and when the body parts (2,3) locating inside the refusesack is lowered onto said bottom part the lowering causes between thebody parts (2),(3) a mutual motion in vertical direction, wherein atleast one wall (3) of the walls moves also sideways due to the diagonaldirected hole (4).
 4. An arrangement according to claim 1 characterizedin that it comprises two movable walls (3) in the opposite sides of saidrefuse sack and the walls is arranged to move towards each other whenthe walls (3) is lifted up by means of grip taken from the other bodyparts (2).
 5. An arrangement according to claim 1 characterized in thatmovable body parts (3) are fitted to move away from each other whenlowered them down onto to the bottom part of the container constructionby arranging movable wall (3) at first to touch the bottom part and thelater lowering of the other body part (2) down towards the bottom partcauses, due to the diagonal mutual fastening, a transversal motion tothe wall (3).
 6. An arrangement according to claim 1 characterized inthat the transversal motion of the wall (3) is arranged to make theresidue sack (6) to strain around the body parts (2), (3).
 7. Anarrangement according to claim 1 characterized in that residue sack (6)forms at least partly the outer surface for the container mantle.
